CLOSURE.

SPECIFICATION forming part of Letters Patent No. 568,774, dated October6, 1896. Application filed September 27,1895. Renewed July 22, 1896.Serial No. 600,177. (No model.)

To all whom it may concern..-

Be it known that we, ALBERT S. LAMBERT and EDMUND HOFFMAN, citizens ofthe United States, residing at Bridgeton, in the county of Cumberland,in the State of New Jersey, have invented a certain new and usefulImprovement in Olosures,of which the following specification is a trueand exact description, reference being had to the acoompanyin gdrawings, which form a part thereof.

Our invention relates to closures or stoppers for bottles, cans, or likereceptacles, our object being to provide a simple and efficientlocking-closure of novel construction.

The nature of our improvements will be best nnderstood'as described inconnection with the drawings, in which they are illustrated, and inwhich Figure 1 is a central longitudinal section through a bottle-neckand through our closure shown in connection with it. Fig. 2 is a similarsectional view of the closure, taken at right angles to the section ofFig. 1 and showing the two parts of the metallic closure assembled butnot secured together. Fig. 3 is a top view of the closure; Fig. 4, aplan view of the lug-carrying ring which forms a part of the closure,and Fig. 5 a sectional perspective view of the bottle-neck adapted foruse with our closure.

A indicates the bottle-neek,which is formed with twodownwardly-extending and oppositely-disposed grooves A, terminating incircumferential grooves A formed with downwardly-sloping upper walls A15 is the metallic closure, which is formed with a depressed centralportion B adapted to enter the mouth of the bottle or other receptaclewith which the closure is used, a circumferential shoulder B extendingaround the bottom of this depressed portion, and a depressed bead Bbeing formed inside of the shoulder B 0 is a metallic ring adapted tofit around the head 13 and to be clamped between the bead and theshoulder B As shown in Fig. 1, the ring 0 is provided withoutwardly-extending lugs O, which are the locking-lugs of the closure,and of these lugs there may be two or any desired number. Extendingoutward from the depressed portion B of the closure is a portion B inwhich or between whichand the top of the bottle or other receptacle weprefer to secure a washer, as indicated at E, and preferably we form adownwardly-extending and corrugated rim B on the outside of this portionB In using the closure the washer E is either placed and secured againstthe portion B of the closure or placed on the top of the bottle. Thelugs C are then brought to register with the grooves A and the depressedportion B inserted in the neck of the bottle or opening of the can orother receptacle. The lugs 0 being brought to register with thecircumferential grooves A the closure is turned so that the lugs passinto the said grooves, and pressing against the inclined walls A theydraw the closure downward and compress the washer E between the neck ofthe bottle and the portion A of the closure, thus securing a tightclosure. A reverse movement of theclosure of course withdraws it fromthe bottle.

Having now described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

A closure-cap formed of sheet metal having a depressed central portion13 formed with a shoulder B and dependent flange B in combination with aring 0 having outwardly-extending lugs C clamped between the shoulder 13and flange B 7 ALBERTS. LAMBERT.
